Used as a fluorescent probe in biochemical and cellular imaging due to its strong photostability and emission in the visible range. It binds selectively to specific DNA sequences, making it valuable in studying nucleic acid structures and interactions. Also employed in the development of organic semiconductors and optoelectronic materials because of its extended π-conjugated system. Its bromine functionality allows for further chemical modifications via cross-coupling reactions, enabling use in synthetic pathways for complex heterocyclic compounds.
